Te tikanga whakaputa

Ka whiwhi mā te whakaiti i te p-nitroaniline me te paura rino i roto i te reo waikawa. Tāpirihia te paura rino ki roto i te waikawa hauwaiora, whakamahanahia ki te 90°C, ka tāpirihia te p-nitroaniline me te whakaoho. Kia oti te tāpiri, tauhohe ki te 95-100°C mō te 0.5 hāora, kātahi ka tāpirihia te waikawa hauwaiora kukū kia maturuturu iho hei whakaoti i te tauhohenga whakaiti Chemicalbook. Kia whakamatao, whakakorea ki te wai konutai kāponāte kukū ki te pH 7-8, kohuatia, ka tātarihia i te mea e wera ana, ka horoia te keke tātari ki te wai wera. Whakakotahitia te tātari me te wai horoi, whakakorikoria i raro i te pēhanga iti, whakatio mā te whakamatao, whakahoro rānei i raro i te pēhanga iti hei whiwhi i te p-phenylenediamine me te hua o te 95%.
